KANSAS CITY, Mo. — The Interstate 435/Interstate 70 interchange project will force a major closure on I-70 starting Sept. 6.
The interstate will be closed in both directions between I-435 and Interstate 470/Route 291 beginning at 9 p.m. on Friday, Sept. 6 through 5 a.m. on Monday, Sept. 9.
During the closure, crews will demolish two more ramps at the I-435/I-70 intersection. They will be tearing down the ramp from southbound I-435 to eastbound I-70 and the ramp from northbound I-435 to westbound I-70.
To ease congestion, MoDOT will be removing the left exits, replacing bridges and improving the loop ramps at the interchange. The full project is expected to be completed by December of 2020.
While the interstate is closed down, MoDOT will be performing other maintenance work in the area including lighting repairs, median barrier wall repairs, drainage work and paving.
Here's what to expect and when:
Thursday, Sept. 5: Crews will close the ramps from northbound I-435 to westbound I-70 and the ramp from southbound I-435 to eastbound I-70 starting at 7 p.m. These ramps will remain closed until approximately spring 2020.
Friday, Sept. 6: Crews will begin reducing lanes of I-70 to just one lane in both directions between I-435 and I-470/Route 291 starting around 7 p.m.
